I think people are confused - 2.3 was not released today - only the SDK - which does not make a ROM nor a stock O/S - it only helps developers get prepared for when the Source Codes and Update is Officially Released

tp76 is correct. However, the SDK Emulator contains pre-compiled Gingerbread source code, including the system.img that has the system folders (framework, etc). So, a skilled dev could take that, mix it with a modified boot.img, sprinkle in some drivers, and viola. It might be out sooner than you think...

As far as i've read, the SDK was released about a month ago to Devs, and the actual OS has started being pushed to N1 users today as of 10:00am EST. One of my friends has a N1 and showed me the OTA update notification. Waiting for it to finish DLing now.
